Stop areas are supposed to link stop positions to platforms, so a router 
knows which platform you need to take a route that only stops on a 
particular track.  In most cases, this can be inferred by proximity, but 
in some it can't, particularly at very complex stations.

If an entrance serves a subset of platforms (i.e. you might have to 
leave and re-enter via a different door to change trains), then it might 
make sense in a stop area, but otherwise, it's just part of the station.
